I don't know what it is either but I have it in one area of my garden and I try to pull it up before it flowers because they hurt your hands if you don't. Mine has flowers along the stems of the weed, not on top of the stem. Some call it beggars lice but I think that is a different weed.

That is the juvenile form of beggars lice.

The one on my property is Torilis nodosa.

Thanks everyone! Pretty sure it's Torilis Arvensis.

Yes, it looks like Beggars Ticks, as I call it. Too bad freezing weather won't kill it.

Mature plants are killed by the cold in my area, but they produce zillions of seeds.

Last spring , I had a huge crop of it everywhere and I tore it out all spring and hauled it off to the compost heap. When it flowered I pulled the seed heads and bagged them and composted the rest. Irritating plant. Bugs,beetles, flies, bees and butterflies seem to like it. They seem to die in the summer heat and dryness here.

This may or may not have been the weed that didn't survive six plus inches of leaves that were dumped in their growing area in the fall. I left the matted leaves alone there until they disappeared. This didn't phase the bermuda, but it did phase the forbs.

Round up?

I start pulling them as soon as I see them .....like now till the go to seed , then I bag their seeds and pull them and add them to my compost heap. I had a huge pile last year just full of them.
